warblers. Its call note is a sharp chip. Its song is described by Seton 

 as much like that of the Chipping sparrow. Jones describes it as not very- 

 high pitched but full and strong, ending abruptly on a rising scale like 

 the syllables " chee-chee-chee, chw'-chw'."

Description. Upper parts bright olive green; the crown and nape 

 grayish blue; a whitish line over the eye and usually a dusky line through it; 

 inner webs of the 2 outer tail feathers with a margin of white; under parts 

 dull white, the breast often tinged with buffy yellowish; sides greenish. 

 Female: Similar to the male, but the crown washed with the color of 

 the back and the under parts more yellowish. Female and young in the 

 fall: Entirely bright olive green above. Adult male in the fall: Less 

 distinctly bluish gray on the head and neck and under parts more tinged 

 with yellowish. 



Length 4.50-4.80 inches; extent 7.50-8; wing 2.7; tail 1.8; bill .4. 



Distribution. Breeds from southern Mackenzie, central Keewatin, 

 southern Ungava and Anticosti to southern British Columbia, Manitoba, 

 northern Minnesota, Ontario, northern Maine and New Hampshire; 

 winters from Oaxaca to Colombia and Venezuela. In New York this 

 species is a fairly common transient in the fall, even in the eastern portion 

 of the State, but a rare migrant in the spring in southeastern New York, 

 though not especially uncommon in the western portions of the State, 

 arriving in the spring from the loth to the i8th of May, passing northward 

 from the 22d to the 27th, and appearing in the fall from the 15th to the 

 31st of August, departing southward from September 25 to October 8. 

 The latest edition of the A. O. U. Check List records it as breeding in the 

 Adirondacks, as does also Ridgway's " Birds of North and Middle America," 

 evidently on the authority of Doctor Merriam's list of Adirondack birds
